Wiring
Using a wire crimper, crimp u-lugs on the
ends.
b. Using wire strippers, strip the rubber
jacketfrom both ends of the signal cable
to reveal approximately 15cm (5.9”) of
wire.
c. Strip the insulation from the ends.
d.
NOTE:
When connecting the wires, strictly
follow the wiring diagram found inside the
electrical box cover.
2. Remove the electric cover of the outdoor unit.
